National LMX2314/LMX2315 handbook
Update: 30 September, 2023
The LMX2314 and LMX2315 are high performance frequency synthesizers with integrated prescalers designed for RF operation up to 1.2 GHz. They are fabricated using National's ABiC IV BiCMOS process. The LMX2314 and LMX2315 contain dual modulus prescalers which can select either a 64-65 or a 128-129 divide ratio at input frequencies of up to 1.2 GHz. Using a proprietary digital phase locked loop technique, the LMX2314-15's linear phase detector characteristics can generate very stable, low noise local oscillator signals. Serial data is transferred into the LMX2314 and the LMX2315 via a three line MICROWIRE interface (Data, Enable, Clock). Supply voltage can range from 2.7V to 5.5V. The LMX2314 and the LMX2315 feature very low current consumption, typically 6 mA at 3V. The LMX2314 is available in a JEDEC 16-pin surface mount plastic package. The LMX2315 is available in a TSSOP 20-pin surface mount plastic package.
